ruby - 我如何将这个八球脚本转换为红宝石

Question

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var answers = new Array(
"Yes.",
"No.", 
"My sources are pointing toward yes.", 
"It's possible.",
"Very unlikely.", 
"Can you repeat the question?",
"Absolutely not.", 
"Sure.",
"Ask again later."
);
function fortune() {
num = Math.round( (answers.length - 1) * Math.random());
return answers[num];
}
//  End -->
</script>

然后当我调用fortune('text')它时，它会从数组中获取一个值
